fntproof – A programmable font test pattern generator

The pack­age im­ple­ments all the font test­ing com­mands of
Knuth’s test­font.tex, but
ar­ranges that in­for­ma­tion nec­es­sary for each com­mand is sup­plied
as ar­gu­ments to that com­mand, rather than prompted for. This
makes it pos­si­ble to type all the tests in one com­mand line, and
easy to in­put the pack­age in a file and to use the com­mands there.
A few ad­di­tional com­mands sup­port­ing this last pur­pose are also
made avail­able.
